Description

The The present invention relates to a self-supporting sliding door with a door leaf, whose lower part by a hollow, laterally or bottom open support profile is formed, with at least one stationary laterally mounted next to a door opening support roller assembly with at least one lying in the hollow interior of the support profile Carrying roller and with a distance from the support roller assembly also Fixed laterally next to the door opening, in the hollow interior of the support profile lying drive unit with at least each an upper and lower drive roller, wherein the upper drive roller on an upper track and the lower drive roller on a lower track Runway in the support profile is applied, the drive rollers in the longitudinal direction of the support profile spaced-apart axes of rotation, wherein the drive unit to a transversely to the longitudinal direction of the support profile extending horizontal pivot bearing is pivotable and where the pivot bearing on a standing on the floor bearing support is arranged.

A sliding gate of the type mentioned above is made EP 0 711 898 A1 known. This known sliding gate has proven itself in its practical use and is characterized in particular by a reliable drive and a due to the concealed arrangement of the drive in the support profile achieved particularly good external appearance image. The load of the door leaf is thereby taken up by the non-driven carrying roller and, depending on the displacement position of the door leaf, by one or the other drive roller. This results in large point loads due to relatively small contact surfaces between the support profile on the one hand and the rollers on the other hand, especially in large sliding doors cause the loads for the drive are too large.

For The present invention therefore has as its object, a sliding gate of the type mentioned above to provide the above Disadvantages and in particular in the case of large, especially extra long door leaves lower loads be achieved for the drive and where the support profile can be performed with a lower weight, where ensure safe operation of the sliding door should.

The Solution of this task succeeds according to the invention a sliding gate of the type mentioned, characterized is that at least one support roller at a distance from the drive unit is arranged, which is coupled to a hinged to the drive unit Rocker arrangement is stored.

With the construction according to the invention are the Relieves drive rollers from a part of the weight of the door leaf, because now part of the weight of the at least one carrying roller, which is assigned to the drive unit is accepted. Due to the arrangement of the support roller on the articulated coupled to the drive unit Rocker arrangement becomes at any time an automatic load distribution on one of the two drive rollers on the one hand and the at least achieved a support role on the other. The remaining share of Weight of the door leaf, which acts on one of the two drive rollers, is enough for a reliable drive force transmission from the drive unit via the drive rollers on the In any case, the support profile of the door leaf, making a reliable Drive is guaranteed. At the same time, the burdens, which act on the drive and on the support profile in the contact area acting on the rollers, reduced, since the weight of the Torblatt now is distributed across several roles. This allows a lighter version the supporting profile of the door leaf and / or an execution made of less solid material, which saves material costs and what for the sliding door drive a lower drive power allowed. So the door leaf with the support profile z. B. now easily Made of aluminum, which is high for taking Point loads is poorly suited, but offers significant weight advantages. Here are, as already known in the above-described Sliding gate, all parts of the drive and also the additional Rocker arrangement with the at least one carrying roller within the housed hollow support profiles, allowing them from the outside are not visible and against external influences, especially weather conditions, well protected are.

A first concrete embodiment of the sliding gate according to the invention proposes that the rocker assembly is formed by a single rocker, which is pivotally coupled at its one end to the drive unit about a horizontal transverse axis which carries at least one support roller at its other end and between their Ends is mounted in a transverse to the longitudinal direction of the support profile extending horizontal pivot bearing on a standing on the ground rocker support. In this embodiment, the sliding gate requires only a single rocker and an additional support roller to achieve the beneficial relief effect. Instead of a single support roller can here, as well as in the embodiments to be described below, instead of a roller and a pair of rollers are used, the rollers are arranged on a common axis. A desired distribution of the weight recorded in the region of the drive unit by its drive rollers and the additional roller provided here can be determined by ge suitable selection of the lever arm lengths of the rocker. The weight distribution does not have to be 50% to 50%, but can also deviate from this.

A Other embodiment of the sliding door according to the invention provides that the rocker arrangement is formed by two rockers, wherein the first rocker at its one end to the drive unit and at the other end with the second seesaw between their ends is coupled in each case pivotable about a horizontal transverse axis and in a direction transverse to the longitudinal direction of the support profile horizontal pivot bearing on a standing on the ground rocker support is mounted and wherein the second rocker at its two ends respectively carries at least one carrying role.

By the drive unit associated rocker assembly 2 with the carrying roller 25 become the drive rollers 15 and 16 the drive unit 1 as well as the support profile 3 relieved and the weight of the door leaf, the lower part of the supporting profile 3 forms is distributed among several roles. This allows the support profile 3 be performed with less material thickness and lighter weight for a given length of the door leaf.

The rocker arrangement 2 Its articulated design ensures that the desired weight distribution is achieved when the weight of the door leaf is taken up by the drive rollers 15 and 16 as well as the carrying role 25 results; In addition, thereby dimensional tolerances and deviations in shape of the support profile 3 automatically compensated, without causing a loss of friction between the drive rollers 15 and 16 on the one hand and the tracks 35 and 36 of the supporting profile 3 on the other hand comes.

The 2 shows a further embodiment of a drive unit 1 with a seesaw arrangement 2 for distributing the weight of the door leaf, whose lower part here is the support profile 3 forms. The drive unit 1 with the engine 10 , the gearbox 11 , the pivot bearing 12 , the bearing support 14 and the two drive rollers 15 and 16 is identical to the one previously in 1 described example.

Also in the example 2 is at the of the pivot bearing 12 remote end of the transmission housing 11 again a coupling joint 23.1 provided by means of which one end of a first rocker 20 about a horizontal, transversely to the longitudinal direction L extending axis pivotally connected to the transmission housing 11 connected is. The second end of the first seesaw 20 is with a second seesaw 21 in a second coupling joint 23.2 connected, wherein also the second coupling joint 23.2 forms a horizontally and transversely to the longitudinal direction L extending pivot axis. In the area between their ends is the first seesaw 20 in a pivot bearing 22 on a rocker support 24 pivotally mounted, wherein the pivot axis of this pivot bearing 22 also horizontally and transversely to the longitudinal direction L extends. The rocker support 24 is, as well as the bearing support 14 , on the ground 5 arranged and fixed there.

The second seesaw 21 carries at its two ends on both sides of the second coupling joint 23.2 one carrying roller each 25 and 26 , The carrying roles 25 and 26 again have a diameter that is only slightly smaller than the distance between the upper raceway 35 and the lower raceway 36 in the supporting profile 3 ,

Through this rocker arrangement 2 with two seesaws 20 and 21 an even greater load distribution is achieved because now the weight of the door leaf with the support profile 3 on a total of three roles, namely one of the two drive rollers 15 and 16 as well as the two carrying rollers 25 and 26 , is distributed. This will be the individual roles and the support profile 3 relieved and must therefore be carried out less stable. This saves material costs and weight.

Also in the execution of the drive unit 1 and the seesaw arrangement 2 according to 2 can one of the supports 14 and 24 or both supports 14 and 24 be height adjustable to the arrangement of drive unit 1 and seesaw arrangement 2 to adjust properly. Desired weight distributions are also here by the choice of Hebelarmlängen the rockers 20 and 21 set.

The pivot axis of the coupling joint 23.1 runs hori zontal and transverse to the longitudinal direction L of the support profile 3 , At the other end carries the first seesaw 20 a first rotatable carrying roller 25 , In their area between the coupling joint 23.1 and the first carrying role 25 is the first seesaw 20 by means of a second coupling joint 23.2 with the second seesaw 21 pivotally connected. The pivot axis of the second coupling joint 23.2 also runs horizontally and transversely to the longitudinal direction L.

The second seesaw 21 carries on her other, from the second coupling joint 23.2 distant end a second carrying role 26 , In the area between the second coupling joint 23.2 and the second carrying roller 26 is the second seesaw 21 in a pivot bearing 22 on a rocker support 24 pivoted. The pivot axis of the pivot bearing 22 runs horizontally and transversely to the longitudinal direction L. The rocker support 24 is also here as the bearing support 14 , on the ground 5 arranged and fixed.

Also in this embodiment, one of the supports 14 . 24 or both supports 14 and 24 be designed adjustable in height to the arrangement of drive unit 1 with the two drive rollers 15 and 16 as well as the rocker arrangement 2 with the two carrying rollers 25 and 26 relative to the supporting profile 3 to adjust.

As in the example after 2 takes place in the example 3 the weight distribution of the door leaf on now a total of three roles, namely one of the two drive rollers 15 and 16 and the two carrying roles 25 and 26 , Thus, according to this construction 3 the rollers and the supporting profile 3 effectively relieved.

Also in the example 3 are the two carrying roles 25 and 26 designed with a diameter which is only slightly smaller than the distance between the upper track 35 and the lower raceway 36 in the supporting profile 3 , so that depending on the shift position of the door leaf, the carrying rollers 25 and 26 either on the upper track 35 or at the bottom track 36 of the supporting profile 3 abut, without causing the support profile 3 and so that the door leaf can perform a noticeable tilting movement overall.

4 finally shows in the same representation as the 1 to 3 a non-powered support roller assembly 4 , Again, the support profile 3 of the door leaf, otherwise not shown, is shown vertically cut in the longitudinal direction L, the illustration being purely schematic. The carrying roller arrangement 4 consists of a rocker 40 , which at its two ends depending on a carrying role 45 . 46 wearing. In their area between the two carrying rollers 45 . 46 is the seesaw 40 in a pivot bearing 42 on a rocker support 44 pivoted. The pivot axis of the pivot bearing 42 runs horizontally and transversely to the longitudinal direction L, that is perpendicular to the plane of the drawing. The pivot bearing 42 sits at the top of the rocker support 44 coming down from the hollow support profile 3 is led out and on the ground 5 stands and is fixed there.

Also these carrying roles 45 . 46 the support roller assembly 4 have an outer diameter that is slightly smaller than the vertical distance between the upper raceway 35 and the lower raceway 36 in the supporting profile 3 , Thus, the support profile sets 3 also in the field of support roller assembly 4 depending on the current displacement position of the door leaf either to the top of the idlers 45 . 46 or to the bottom of the idlers 45 . 46 without the support profile 3 and so that the door leaf can perform a noticeable tilting movement overall.

With the support roller arrangement 4 is also in the field of non-powered support of the support profile 3 and the other door leaf achieved a better load distribution, since now the weight of the door leaf on the support profile 3 is distributed on at least two carrying roles.

In a similar manner as in the examples according to 2 and 3 can the idler assembly 4 according to 4 also be supplemented by one or even several rockers. For each additional rocker another support roller can be arranged so that a desired distribution of the weight of the door leaf is achieved as needed.
